POOL-TABLE.

Specification of Letters Patent.

Patented J an. 2, 1917.

To all whom it may concern Be it known that we, JOSEPH P. SORENSEN andROYDEN THORNBERG, citizens of the United States, residing at SanFrancisco, in the county of San Francisco, State of Cali fornia, haveinvented a new and useful Pool-Table, of which the following is aspecification in such full and clear terms as will enable those skilledin the art to construct and use the same.

This invention relates to a pool table and its object is to deliver theballs claimed by each player in separate pockets thereby enabling eachplayer to know just how many balls he has obtained without the necessityof gathering the balls up after each play. The above object is attainedby means of an electrically operated apparatus which is shifted by eachplayer so that the balls played by him will be discharged in his pocket.

An embodiment of the invention is shown in the drawing in which the samereference numeral is applied to the same portion throughout, but we areaware that there are many modifications thereof.

Figure 1 is a side elevation of the table, each side appearingsubstantially the same as in Fig. 1, Fig. 2 is a plan view of the tablewith the cushions and top removed therefrom, Fig. 3 is a verticalsectional view of the table on the line 3-3 Fig. 2, Fig. 3 is a brokenperspective view partly in section of the distributing apparatusadjacent the center of the table. Fig. 4 is a vertical sectional view onthe line H Fig. 2, Fig. 5 is an end view of the table, each endappearing substantially the same as in Fig. 5, Fig. 6 is a diagrammaticview of the electrical wiring of the table, Fig. 7 is a plan view of thetable showing the lower set of chutes which deliver the separated ballsto the individual pockets, which sends the balls to the individualchutes, Fig. 9 is a plan View of one of the relay armatures, Fig. 9 is aside elevation of one of the relays showing the relation of its contactmaking devices. Fig. 10 is a plan view of one of the contact brushes.

The numeral l represents the table legs, said legs being connected bymeans of stringers 2 and connected at their upper ends with arectangular frame work 3, which supports cushions 4 and top 5. The cushions and top are connected with each other Fig. 8 is a side elevation ofthe cup and are removably secured to the frame work 3. At the bottom ofthe frame work 3 there is a floor 6 which floor affords a support forthe six inclined troughs 7 to 12 inelusive, said troughs extending fromthe usual pockets at the corners and sides of the table to the centralopening in the floor 6.

The stringers 2 connecting the lower portion of the table legs support afloor 13 upon which floor the electrical apparatus and mechanicalapparatus for the operation of the ball switch is installed. Near thecenter of the floor 13 there is an inverted U shaped frame 14 whichrests upon the floor and forms a support for a block 15. This block hasaplurality of members 16 which extend upwardly through the floor 6 toclose the space between the four chutes 17 to 20 incluslve. The chutes17 to 20 inclusive are supported at one end on the block 15 and at theother end each chute is supported on a short post as indicated at 21,22, 23 and 24, the ends of the chutes projecting through the doors 25to'28 respectively. The doors 25 to 28 inclusive are hinged at one endas indicated at 29 and 30 and a suitable catch, not shown, is used tohold them closed. On each door a cup 31 is secured adjacent the openingthrough which the chutes project, said cup' being for the purpose ofreceiving the pool balls as they may be discharged through the chuteleading thereto.

The members 16 form a circular chamber within which a cylindrical cup 33having an inclined bottom is mounted, said cup having an opening 33 onone side for the discharge of the balls rolling thereinto to any one ofthe chutes 17 to 20 inclusive. The cup 33 is mounted upon a verticalshaft 34, which shaft has a bearing 35 on the floor 13.

The shaft 34 is provided with a gear wheel 36, which gear wheel is inmesh with a worm 37 on the shaft 38 of the motor M. The worm wheel shaftis also provided with a bearing 39 mounted upon the floor 13. Alsomounted on the shaft 34 is a fiber disk 40. This disk has a ring 41thereon which ring is cut at 42 and in contact with which ring thebrushes 43, 44, 45 and 46 operate. The brushes 43 to 46 inclusive aresecured to the floor 13 in any suitable manner and are in turn connectedwith the electric wiring in a manner that will be explained later.

Mounted on the side framing 3 of the table are-the push buttons ,48,'49and said push buttons being for the purpose of enabling any playerto'set the apparatus so that the balls played by him intothe pockets inthe pool table Will be discharged into his individual receptacle. 7

In order to enable the. proprietor to disconnect the electricalapparatus at Will the r uponthefioor l3 and connected with theelectrical circuits.

mounted upon the floor 13 for the purpose door 25 is provided with asuitabletvvo point 7' switch '51, which switch is connected withtheelectrlc Wiring system in awvell known manner as will be explained inthe Wiring diagram. q

In order thatthe motor may be operated four relays52, 53, 54 and 55 aremounted Another relay 56 is also 'of'closing the circuit on the pilotlight 57 to enable the players to knoiv'ivhen a play may be made, saidlight indicatingthat the apparatus isin motion.

In order to enable all of the players to see When the apparatus ismoving an extension of thewires carrying the current is made to eachside of the table so that one of the.

' lights 57 shows at each side and end of the r 1 table.

V In the wiring diagram, F g. 6, 34 indicates the shaft carrying thedisk 40upon which disk the ring41' is mounted. 'The brushes.

are indicated at 43 to 46 inclusive With 7 ,Which brush Wires 60, 61, 62and '63 are'connected, each of said Wires extending to the relays. Therelays 52 to 55 respectively are of'acommon form.

, l in Figs. '9 and 9 the parts or the relays r are illustrated, 52indicating the coil, 64 a I base upon Which the coil is mounted, whichbase carries a pivot 'rod 64 for the armature 64%, said armature havinga rearwardly extending portion64 Which engages the contact point 64 whenthe armature is raised V by the magnet 52. The Wires from the brushes 43to 46. inclusive extend to the relays52 to inclusive from the oppositesides of which Wires 70, 71, 72 and 73 6X1 tend'to the push buttons.From the oppo'- site side ofthe push buttons, Wires 7 4, '7 5,

76 and 77 extend to the ires 78, 7 9, 80' and 81, all connected togetherby means of the ire 82, which Wire extends to the battery B. Thenumerals 65, 66 and 67 indicate the armatures of the-remaining relays,there be-' '-'ing one relay. for each player and'set of .individualtroughs.

'Each' ofr he relay ar atures cuts out the adjacent push button heneverthat pari j ticular push button has been closed, so that.

when once one of thepush buttons is closed the relay will hold thecircuit closed. until it is broken at some otherplace, as will *be.filater explained. Extending from: e ppo site side of the'battery is awire 83 cjonnected'f] into the switch .51, a Wire 85 extending to lightsWill go out indicatingthat theappathe motor M from the oppositeside'ofrwhich'r 1 the Wire 86 extends to the shaft 34.2mm 87 connectingthe ring 41 with the slia.ft 34. In order to prevent irregular currents8 from the motor from. interfering With the operation of the relays 52to 55 inclusive,

a shunt relay 56 is provided across the 1110- tor. This relay has Wires88 and 89 connect mg it with the Wires 85 and 86. Itoperates an armature90, which armature connects a the vvi1'e'91wvith an extension of theWire 82,

said Wire 91 extending to the'lamp's 57, and it at the same timeprovidesthe pathffor the current to'hold the armatures of the relays up. On theopposite side 'ofthe'lamps 1 from the Wire 91', a Wire 92 extendsftothe7 Wire 85. r

The result ofthe foregoing construction is 7 that 'i'vhenever .one ofthe 'push' buttons closes a circuit that its relay armature vvilll bepicked up and the circuit' Will remain closed until the motor has turnedthe shaft 34 and assembled parts to the desired; position, Which is thatposition determined by the particular relay circuit energized and: itsparticular brush 43 to 46 Whichever may happen to be passing current. Atthe'sarne time that .the push button is operated. the

relay 56 will be operated and the lamps 57,

Will glow, thus indicatingthat the {apparatus is in motion and that aplay is not to be made. As soon as the opening in the the circuit willbe broken and'both of the relays Willdroptheir' armature's and the motorWill stop,' thus;leaving the segregating cup in the desired position todeliver;

ring 41 reaches the brush pas'singicurrent 7 the balls played totheproper playerf As 1 soon as the relays droptheir armaturesJthe Vratus is ready for the play to take place.

7 Having thus described our invention what f We claim as new and desireto secure by Letters Patent of: the United .smes',;is as follows,modificationswithin the scope of the claims being'iexpressly reserved 1.In a pool table, the combination of a table having a'plurality ofpockets, a ,dis-
